An expendable remote initiator receiver for initiating at least one shock tube connectable to an explosive charge. The receiver includes a shock tube interface that directly interfaces with a shock tube connected to an explosive charge, a spark initiator that initiates a spark at the shock tube interface to initiate the shock tube, a multifunctional shock tube interface adaptor mounted and connected to the shock tube interface, wherein the multifunctional shock tube interface connects the ground of a printed circuit assembly (PCA) to the shock tube needle to allow a spark to occur upon initiation by the spark initiator and also holds the PCA securely. The remote initiator further includes configuring means adapted to allow the receiver to be field bondable such that the receiver can be configured to any transmitter, zeroizer configured by software to allow the configuration of the receiver to be blanked so that the receiver cannot be initiated by any transmitter until such time as the receiver is field-bonded by the configuration means, a multifunctional battery cap adapted to withstand ±25 KV electrical static discharge (ESD) events and allows for the receiver to stand upright, and an antenna capable of withstanding ±25 KV ESD events. |

Explosive cutter assemblies and methods include a liner having a single unitary body, and an explosive charge disposed within the liner. The explosive charge includes a continuous unitary body of explosive material having a first area disposed in association with an inner surface of the liner and a second area extending from the center of the assembly to the first area. A detonator can be used to ignite the second area of explosive material, causing propagation of a detonation to the first area, which in turn causes deformation of the liner and projection of the liner toward a target to form a cut. An adaptor sub having a detonator within can be inserted into the cutter assembly to secure the assembly together, position the detonator in association with the explosive material, and engage a conduit usable to raise and lower the cutter assembly and transmit a detonation signal. |

The present invention describes an electronic fuze operable to complement a mechanical point impact fuze. The electronic fuze includes a voltage generator circuit, micro-controller, a piezo-electric sensor, a firing circuit and a safety lockout circuit. When a projectile strikes a target at an optimum angle, the mechanical point impact fuze is activated; when the strike angle is oblique, the mechanical point impact fuze may be ineffective but the piezo-electric sensor is operable to trigger the firing circuit. The safety lockout circuit ensures the firing circuit is operative only after a predetermined delay time when an n-channel FET is turned OFF. The micro-controller also generates a TIME-OUT signal, which provides for self-destruction of a projectile that has failed to explode. |

An unmanned aerial vehicle is equipped to carry a payload of explosives for remote delivery upon a target. The vehicle includes a small TV camera, global positioning system, and auto pilot homing target software. The modified vehicle is capable of being detonated upon an impact or selectively while still in flight. Vehicle flight is monitored by an operation person at a ground control station. The vehicle includes universal smart fuze circuitry for enabling the multiple functions for the vehicle and for enabling communications/commands from the operator at the ground control station. The fuze continuously communicates aspects of fuze status back to the ground control station; measures flight velocity by sensing air speed of the UAV; arms/disarms an explosives warhead package in the vehicle; in flight fires the explosives or else detonates the explosives warhead package upon impact with a select target. The camera images are communicated back to the operator who can make a decision on completing/aborting a mission. The wind speed indications, also fed back to the operator, can further aid in verifying a successful launch/good flight for decision of completing/aborting a mission. |

An explosives detonator system includes a detonator housing within which is provided a detonation circuit that includes a conductive pathway having a fuse head integrated therewith such that the conductive pathway passes along both electrodes and a resistive bridge of the fuse head. An uncharged chargeable voltage source is also integrated with the detonation circuit and is electrically sensitive to a charging property which is included in a charging signal. Exposure to the charging property charges the voltage source, thereby rendering it capable of generating a potential difference between the electrodes at least to equal the breakdown voltage of the resistive bridge. The charging property is any one or more of a charging light pulse, a charging temperature, a charging pressure and a charging radio frequency. |
